Abstract: The present disclosure provides a method for reporting CSI in a wireless communication system. In the present disclosure, a method for reporting channel state information (CSI) in a wireless communication system, which is performed by a UE includes: receiving, from an eNB, downlink control information (DCI) indicating activation of semi-persistent (SP) CSI reporting, in which the downlink control information is scrambled with a specific RNTI distinguished from a Cell-Radio Network Temporary Identity (C-RNTI); and reporting, to the eNB, the semi-persistent CSI through a physical uplink shared channel (PUSCH) based on the received downlink control information.

Abstract: A method for receiving a signal by a user equipment (UE) in a wireless communication system is discussed. The method includes receiving, from a base station (BS), control information; and receiving, from the BS, downlink data on an unlicensed band cell (UCell) based on the control information. Further, in case of: the control information received on another serving cell, the downlink data is received in a first time resource, and the control information received on the UCell, the downlink data is received in a second time resource, and the second time resource is smaller than the first time resource.
